Type 703 & Type 705 Series Fiberglas™ Insulation Boards

Description

Owens Corning® Fiberglas™ 703 and 705 Series Insulation boards provide thermal and acoustical insulation for mechanical equipment, air ducts, walls, and ceilings. Composed of resilient, inorganic glass fibers, these semi-rigid (703) and rigid (705) boards offer reliable heat and sound control with a clean, finished appearance, especially in high-abuse areas. With ASJ Max or FRK facings as vapor retarders, they’re suitable for a range of applications requiring durability, resistance to moisture, and ease of installation.
